Dynaudio Heritage + Gold Note IS-1000 Deluxe

I would look for something that truly doubles its power into 4 ohms. The specs on this don’t even give a 4 ohm rating that I can see in the spec list. 
 

that said would probably be ok but maybe not ideal. 

I’ve had Focus 140s and Contour 20s. Odyssey Audio amps worked really well. Lyngdorf integrated ran out of juice really quick on the Contours. Wish I could have heard them with a more beefy amp. 
i did hear some Contour 60s with an Octave V110 or V80 and it was really good. Sounded thick and detailed and dynamic. Good stuff. 

I had the smaller Lyngdorf 2170 with the Contour 20s for a while. Not enough power. Ran out of juice quick. Same amp sounded amazing with Tekton DIs. Maybe the more powerful 3400 would have enough.
